类 RocketMqMessageListSplitter

java.lang.Object

sviolet.slate.common.helper.rocketmq.producer.RocketMqMessageListSplitter

所有已实现的接口:

java.util.Iterator<java.util.List<org.apache.rocketmq.common.message.Message>>

public class RocketMqMessageListSplitter
extends java.lang.Object
implements java.util.Iterator<java.util.List<org.apache.rocketmq.common.message.Message>>

用于将RocketMQ的批量消息拆分成1M, 进行分批发送(官方DEMO)

//Messages of the same batch should have: same topic, same waitStoreMsgOK and no schedule support. String topic = "simple"; List messages = new ArrayList<>(); messages.add(new Message(topic, "A", "Hello batch 1".getBytes())); messages.add(new Message(topic, "B", "Hello batch 2".getBytes())); messages.add(new Message(topic, "C", "Hello batch 3".getBytes())); MessageListSplitter splitter = new MessageListSplitter(messages); while (splitter.hasNext()) { List listItem = splitter.next(); defaultProducer.send(listItem); }
